I am getting new car seats (replacements after the wreck). I am getting the frontier 90 again for DD. DS - I am struggling. He is 5 1/2, 47 inches and 48(ish) pounds. Before he had a britax parkway Booster. Would you purchase that again or a britax frontier 90, used as a booster? When do they go to a backless booster? I will admit I am overly paranoid after the wreck.
